Definitions

  • the invention relates to a method for winding from a winding device supplied, strip or thread-like winding material in cross-winding with precision winding, in which the integrals of the angular velocity (pulses) of the coil are detected by a first sensor and added in a first assigned counter and the integrals the angular velocity (impulses) of the traversing thread guide drive is detected with a second sensor and added in a second assigned counter, the sums of the integrals of the angular velocity are compared with one another and the drive of the traversing thread guide is regulated as a function thereof.
  • the invention also shows a winding device for performing the method. Thread-like winding material is understood to mean in particular yarns or tapes.
  • a method of the type described in the opening paragraph is known from US Pat. No. 4,093,146. Special sensors that emit impulses are used. A gear is provided between the drive of the coil and the pulse generator, with which the winding ratio is determined. The registered impulses are only used to control a stepper motor that drives the traversing thread guide. The use of the stepper motor serves to change the width swept by the traversing thread guide. As a result of the use of the gearwheel having a gear, the winding-up method has all the disadvantages which will be explained in more detail.
  • a method and a winding device are known, in which cross winding is used in a graduated precision winding.
  • a first tachometer is assigned to the coil or the winding spindle Detects the speed of the coil per unit of time and passes it on to a controller.
  • the drive of the traversing thread guide is also equipped with a tachometer.
  • the two values of the tachometer are compared and fed to a controller, which in turn influences the drive motor of the traversing thread guide.
  • the use of tachometers has several disadvantages. They have to be calibrated at regular intervals, work depending on the temperature and their accuracy allows the maintenance of a special winding ratio only to a limited extent.
  • a tachometer is an analog measuring instrument, which is due to its design inaccurate.
  • EP-OS 194 524 also shows a method for winding threads in cross-winder with a graduated precision winding.
  • the bobbin ratios In order to achieve optimal thread placement on the bobbin, the bobbin ratios not only have to be precalculated with great accuracy, but must also be adhered to exactly. Since the electrical and electronic measurement and control technology, which are limited for measuring the speeds and maintaining the proportionality between the drive of the winding spindle and the drive of the traversing thread guide, the modulation of the winding ratio in each winding phase is proposed to improve the winding structure.
  • the modulation width should be less than 0.1%.
  • the winding device produces a bobbin from the material being fed, which, depending on the design of the winding device, can have a wide variety of shapes, as shown in FIGS. 1 to 11.
  • Figures 1 to 4 show coils in parallel winding: the material to be wound is wound up with turns lying directly next to one another, the pitch of the material to be wound on the tube or spool corresponds approximately to the diameter / width of the material to be wound. So that the ware does not slip on the sides of such a coil, special measures are required, such as. B. the support of the windings by means of flanges on the winding tube, as shown in Figure 1, and / or by means of a special form of the coil structure, for. B. a bevel of the end faces of the coil, as shown in Figures 2, 3 and 4.
  • FIGS. 5 to 11 show bobbins in cross winding: the material to be wound is laid on the sleeve or bobbin with a large slope relative to the diameter / width of the material to be wound. In this way, more or less rounded reversal points of the material to be wound are formed on the end faces of the bobbin. Since these would be covered by the subsequent turns of the items to be rinsed, the end of the items to be ripped off is prevented.
  • the end faces of the coils can also have a special shape, e.g. B. have a bevel, as shown in Figures 6 and 7.
  • Both the sleeves and the coils do not necessarily have to have a cylindrical shape, they can also, for. B. be conical, as shown in Figures 8 to 11.
  • a winding device mainly has a spindle that winds the material to be wound on a winding tube that may be required, i.e. the winding spindle, and a laying element that reciprocates the material to be wound in the longitudinal direction of the winding spindle within a certain range, the winding width or the stroke moved.
  • the winding spindle can be driven by the circumferential drive on the spool forming on the winding spindle, as in FIG. 12 in Front view and top view schematically shows, or be driven by direct drive of the winding spindle, as shown schematically in Figure 13 in front view and top view.
  • the rotations of the winding spindle 1 or 9 and the linear movement of the traversing thread guide 7 or 13 in the laying member 6 or 14 can have different relationships to one another. This results in a fundamentally different structure of the coil.
  • a bobbin construction according to FIG. 14 results, which is referred to as cross winding with a wild winding.
  • the selected initial pitch angle 16 of the material to be wound on the winding tube 17 - start of the winding process the winding travel - remains constant until the end of the winding travel, the largest diameter of the bobbin 18 - final pitch angle 19 -, the number of turns 20 and 21 to the winding width 22 is steadily decreasing.
  • a bobbin with different packing density of the bobbin material is created for each bobbin diameter.
  • the result is a coil with a constant packing density of the coil material for each coil diameter.
  • Helical gear 15 of FIG. 13 gives a corresponding ratio of a double stroke of the traversing thread guide 13 to the number of revolutions of the winding spindle 9.
  • Double stroke denotes the path of the traversing thread guide 13 from one end of the winding width 22 (in FIG. 14) to the other end and back again.
  • the ratio of 1 double stroke to the number of spindle revolutions is called the winding ratio.
  • FIG. 16 schematically shows a bobbin 23 with a bobbin 24 with a few layers of the items to be wound 25 in a closed, precision cross winding: the items to be wound 25 are deposited on the bobbin 25 after each double stroke in the order of points 26 to 32. Points 26 to 32 represent the reversal points of the material to be wound on one end face of the coil 23.
  • B. 1 5.
  • the proportion that results from the thickness or width of the material to be wound must also be calculated, so that the individual layers of the ware come to lie exactly next to each other and do not lie exactly on top of each other.
  • FIG. 17 shows, as a further example, a bobbin 33 with a bobbin tube 34 and a few layers of the bobbin 35 in a precision diamond winding.
  • the individual layers of the items to be wound 35 are stored here on the spool 33 in the order of points 36 to 40.
  • the dotted line indicates the sequence in which the winding material 35 is deposited on the end face of the coil 33: starting at point 36, only four further reversal points are run through before the winding material 35 at point 37 is again near the starting point, point 36, is filed.
  • another position of the items to be wound 35 is deposited between points 36 and 37 at point 39. There is a defined distance between the individual, adjacent layers of winding material.
  • z. B. is needed for dye spools.
  • the nominal winding ratio is here z. B. 1: 5.2.
  • the portion resulting from the thickness or width of the material to be wound must also be calculated so that the successive layers of the material to be wound come to lie next to one another as desired and do not lie exactly on top of one another.
  • the proportion that results from the thickness or width of the rinsed material so that the successive layers of the rinsed material come next to one another as desired is referred to as the ⁇ value. If the ⁇ value is negative, a forwarding of the rinsed goods is obtained, as shown in FIG. 18.
  • the winding material 43 is deposited in front of the material 46 located on the coil 45 rotating in the direction of arrow 44. With a positive ⁇ value, on the other hand, there is a backward winding of the rinse material, as shown in FIG.
  • the accumulated winding material 47 is behind that on the in Arranged in the direction of the arrow 48 rotating coil 49.
  • FIG. 20 shows a coil 51 in cross-winding with precision winding with winding sleeve 52 and the direction of rotation arrow 53 to explain FIGS. 21 to 24.
  • the winding material is laid on the sleeve with the initial pitch angle 54 and on the outer coil diameter with the final pitch angle 55.
  • FIG. 21 shows the detail of two tapes lying directly next to one another as an example of items to be wound on the winding tube with the initial pitch angle 56 and the tape width 57.
  • the required ⁇ value 58 results from these two values.
  • two successive layers of the items to be rinsed do not necessarily have to lie close together; they can have an intermediate space, as shown in FIG. 22, or they can - especially in the case of ribbons - also be arranged partially one above the other, as shown in FIG. 23 as a reverse and in FIG.
  • a control gear is often used as a winding gear in practice, for. B. a conoid gear, as shown schematically in Figure 25.
  • the winding ratio can be varied continuously within certain limits.
  • a disadvantage of this transmission is that it is non-positive and therefore slippery and therefore does not meet the required accuracy. Rarely can the setting of the required accuracy be guaranteed and can hardly be transferred to all winding devices of a winding system, which can consist of many winding devices.
  • Another disadvantage is the narrow limits within which the winding ratio can be varied.
  • More recent techniques measure the speeds of the winding spindle and the laying member, compare the measured ratio of the speeds with the required winding ratio and adjust the conoid gear mentioned, for example, when the speed deviation has reached a certain size. The same method is also used if the laying member is driven by a separate motor instead of a conoid gear. In order to initiate the readjustment, there must first be a certain speed deviation between the setpoint and actual value. Until the permitted speed deviation is reached and then until the setpoint and actual value are adjusted to the same value, winding is therefore carried out with an inaccurate winding ratio, which leads to poor winding build-up, if not for the entire winding, at least in some winding diameter ranges.
  • the invention is based on the object of providing a method of the type described at the outset with which winding conditions can be implemented and maintained with an accuracy of at least seven decimal places.
  • this is achieved in the method of the type described in the introduction in that the pulses of the first sensor and the pulses of the second sensor are added in the assigned counters over the entire winding travel, and that the ratio of the resulting sums is permanent with one or more successively preselectable winding ratios are compared and the drive of the traversing thread guide is controlled so that the ratio of the sums of the two assigned counters corresponds to the preselected winding ratio or the winding conditions during the entire winding cycle.
  • the analog, instantaneous detection of the speed of the drives is replaced by a digital detection (pulse detection).
  • a digital detection pulse detection
  • a large number of integrals of the angular velocity (pulses) are processed per revolution of the bobbin and per revolution of the drive of the traversing thread guide. Accuracy increases by increasing the number of pulses. For example, 1024 pulses can be generated and processed per revolution.
  • the drive of the traversing thread guide can be controlled in such a way that an accuracy of +/- 1 angular degree (corresponding to 3 pulses) is permitted or corrected.
  • the integrals of the angular velocities of the winding spindle and the traversing thread guide i.e. the angular steps (impulses) are recorded separately, in a sufficiently high resolution, by separately adding all the impulses received during a winding trip from the drive of the winding spindle and the drive of the traversing thread guide.
  • the counters used are independent of one another and can be designed as hardware and / or software counters. There is a permanent comparison of the sum ratios for agreement with the selected winding ratio by means of a computer, which over a Controller affects the drive of the traversing thread guide. The influencing or regulation is ended as soon as the ratio of the sums of the two counters again corresponds to the winding ratio.
  • the winding device for performing the method is characterized according to the invention in that pulse generators are provided as sensors, counters are arranged downstream of the pulse generators, and that a computer is provided for processing the two counter readings, which is connected to the controller for regulating the drive of the traversing thread guide.
  • the counters have sufficient capacity for the winding travel.
  • FIG. It is a front view and a top view with the bobbin spindle 65, the bobbin 66, the drive motor 67 of the bobbin spindle, the first assigned sensor 68, the first assigned counter 69, the laying member 70, the traversing thread guide 71, the running winding material 72, the drive motor 73 of the laying member, the second assigned sensor 74, the second assigned counter 75, the computer 76 and the controller 77.
  • the two assigned counters 69 and 75 have the value 0.
  • the first assigned counter 69 receives z. B. 1024 pulses per winding spindle revolution and registers them.
  • the second assigned counter 75 still has the value 0.
  • the computer 76 immediately evaluates the value of the first associated counter 69, sets it in relation to the value of the second assigned counter 75 and compares this ratio with the predetermined winding ratio. Because here inevitably one If there is a deviation, the computer immediately activates the controller 77. This then controls the drive motor 73, whereupon the second assigned counter 75 from the second assigned sensor 74 z. B.
  • the computer also receives 1024 pulses per revolution of the drive of the laying member 70.
  • the computer in turn records this value, evaluates it as described above and synchronizes the drive of the laying member 70 via the controller 73 in the sense of the desired winding ratio. This process is repeated continuously, with a clock rate that only allows a deviation of +/- 0.35 to a maximum of 1 angular degree.
